No. 552: Developing equipment to measure radiation dose is advancing through collaboration with university (July 3, 2012)

Horiba, one of Japan’s leading measuring instrument makers, opened up the prospect of the equipment to film the strength of radiation dose coming from a radioactive substance and display it on the screen in alliance with Kyoto University. The company utilized the technology developed by Kyoto University to detect the radiation that a star generates when it explodes at the end of its life. The newly developed equipment can measure such low radiation as 0.05 micro sievert per hour. It is now developing a technology to display the strength in different color in collaboration with Canon. The finished product will be put on the market in 2014 for about 10 million yen.

Mitsubishi Heavy is working on the practical application of a camera to visualize radiation dose in alliance with Nagoya University. They have already built a trial product based on the camera for artificial satellite. They are trying to make it as light as 10 kg so that a worker can carry it easily in the field. Furukawa plans to develop a system to observe the radiation contamination from the sky jointly with Tokyo University in two years. A camera will be incorporated in an unmanned helicopter for pesticide spraying, and the helicopter flies at an altitude between 10-20 m and covers an area of 400-square-meter in less than one minute. The system will exhibit strength in the measurement in the mountain area. Currently, measuring radiation dose is costly and time-consuming because it depends mostly on manual labor with a dosemeter. An effective visualization technology is strongly desired.
